Can elderly advice be taken as a good intention for performing questionable actions?

[Smt. Priyanka asked: In Thrylokya Gita 12 (point no. 19), another example that was mentioned was related to Sage Vyasa. He was advised by elders in the family to extend the race with His younger brother's wives. But, can just elderly advice be counted as legal sex without an official marriage taking place? Sage Vyasa did not have this intention and it was only an inert action performed to extend the race due to the good intentions of elders. This was not the case of cheating on the original spouse as well. But, in terms of Pravrutti, is it considered illegitimate sex, even though elders wanted this to happen? How should people understand this so that this is not exploited in today's context giving a reason for good intentions?]

Swami Replied:- The husbands of the two ladies died and those two husbands were the brothers of Sage Vyaasa. The meeting of Sage Vyaasa with those two widow ladies was just a process of artificial insemination that is done in the present times. This was done in Dvaapara age, in which the customs existed were different in certain concepts. Devaranyaaya was allowed in that age, which is getting issues in emergency from the brother of the husband. This is objected by Sage Paraashara in Kali age (Devarāt ca sutotpattiḥ…- Parāśara Smṛti).
